Oat Flour
Oat flour weighs 120g per cup and can be made at home by blending rolled oats in a food processor until fine. It adds a mild, slightly sweet flavor to baked goods. Oat flour absorbs more moisture than wheat flour, so recipes may need extra liquid. For gluten-free baking, confirm your oat flour is certified gluten-free, as oats are often cross-contaminated during processing. Store in an airtight container for up to three months, or refrigerate for longer shelf life.

03 // WHY IT MATTERS
If your cookies spread, your bread is gummy, or your cake sinks — flour weight is usually why.
A scooped cup of flour can weigh anywhere from 125g to 180g. That's a 44% range — enough to wreck a cake.
Modern recipes use the spoon-and-level method: fluff the flour, spoon it into a dry measuring cup without packing, then sweep flat with a knife.
The scoop method — pushing the cup directly into the bag — packs in 40-50% more flour.
